D9 Video: Andrew Mason Full Session

In this D9 interview with Kara Swisher, hours before Groupon announced its IPO, CEO Andrew Mason wouldn't discuss the company's plans for going public -- in fact, he gave Kara his "death stare" whenever she mentioned it. What he would talk about was the company's new mobile product and its clone competitors, including a Chinese one named "Groupon."
